The Guelaguetza ORO Festival, a showcase of Oaxacan music in Los Angeles, will celebrate its 25th anniversary on Sunday, organizers announced on Tuesday.

The festival will bring together the music of 16 different indigenous groups from Oaxaca and include over 250 dancers in multi-colored traditional outfits and a rendition of the famous “Dance of the Marmots” in which men hold up large balloons adorned with hats made from “the belly of a donkey.”

“The Guelaguetza ORO in Los Angeles was the first festival in the United Stated with indigenous roots, thanks to a group of Oaxacans who committed themselves to organizing it, and not just to wear their traditional outfits, but to find themselves within their traditions, values, and indigenous beginnings,” said Martha Ugarte, Oaxacan activist and a promoter for the festival.

During the festival, which will take place in Lincoln Park in Los Angeles, artisans will demonstrate how to make patterned serapes out of wool, explain how to make specially crafted clay pots, and give lessons on how to weave palm utensils.

Ugarte said that “Guelaguetza comes from the Zapotec word ‘Guendalizaa’ which means ‘an attitude or quality with which one is born: a feeling of acceptance, service, cooperation and love for your neighbor’; it is the feeling of kinship, brotherhood and solidarity.”
